AB - The dependency of renewable energy sources on the weather and climate  increased the interest on bulk energy storage methods to supply firm power.  Pumped-hydro energy storage (PHES) systems are a step ahead among other bulk  energy storage methods because these are more efficient and they have higher  storage capacities. The present study focuses on the use of grid connected  wind-pumped hydro power station to supply energy. A hybrid wind-pumped hydro  storage system was designed and simulated using real data, and economic  analysis was performed by calculating the basic payback period, the net  present value and the internal rate of return. According to the results, it  is found that the hybrid system is actively used and a part of the  electricity is supplied from the wind - pumped hydro system. In addition, it  was obtained that the pumped hydro storage systems are very suitable to be  used together with wind power plants.
